M323.690 Test pin — precision gauge pin Ø 6.90 mm, ±0.001 mm, length 50 mm (Metav IndustryLine)

The M323.690 Test pin is a workshop‑grade precision gauge pin for end‑measurement and dimensional inspection tasks in mechanical workshops and quality control benches.

• High precision ±0.001 mm tolerance
• Diameter Ø 6.90 mm, length 50 mm
• Workshop-grade special steel construction
• Supplied in protective transport case

Accuracy that minimises doubt in final inspection

The core advantage of this gauge pin is its ±0.001 mm specification, which corresponds to a one‑micrometre tolerance and is suitable where sub‑millimetre consistency is required. Such precision supports tighter control limits and reduces the need for corrective rework by providing a stable, measurable reference for bore checks, end‑measurements and comparative gauging. For routine quality assurance, the fine tolerance helps to detect minute deviations that would otherwise pass unnoticed with coarser references, improving process reliability and part conformity.

Robust design made for everyday shop use

Constructed in special steel and delivered in a protective transport case, the pin combines dimensional stability with practical handling. At 50 mm length and Ø 6.90 mm, the geometry is compact and easy to position in fixtures or measuring stands; the light weight aids fast handling during repetitive checks. The workshop‑grade finish resists typical wear from contact measurements and keeps the reference geometry consistent over many cycles, which translates directly into longer service intervals and lower replacement frequency for inspection tools.

Seamless integration into metrology workflows

As a single‑piece gauge pin, the item is intended for straightforward application in end‑measurement, plug checks or as a reference for go/no‑go assemblies. The simple geometry minimises setup time and adapts to standard inspection jigs, allowing measurement technicians to maintain throughput without complex fixtures. The compact form factor also supports mobile inspection tasks on the shop floor, where a quick, repeatable reference improves decision speed. The clear specification and supplied protective case improve traceability and storage, supporting orderly calibration and inventory routines — the M323.690 fits naturally into established metrology procedures.
